However, the fastest seller on the list comes from Rihanna and Calvin Harris's 'We Found Love', which is already sixth on the list despite only being released last month.

Outside the top ten, Katy Perry and Kanye West reside at 13 with the single remix of 'E.T.', Rihanna and David Guetta sit at 14 with 'Who's That Chick' and JLS featuring Dev are at 18 with 'She Makes Me Wanna'.

A final list of the best-selling collaborations of 2011 will be released in the New Year.
